Teardown: Inside Apple's iPhone 5

Apple is considered the leader in the smartphone market. In five years, the company has generated more than $150 billion in revenue from the iPhone family of handsets and accessories, according to research firm Strategy Analytics. More than 100 million iPhones have been sold.

The Cupertino, Calif.-based company clearly doesn't plan to relinquish its standing any time soon. The iPhone 5 is touted by many as the most innovative
iPhone since the original, offering the first
re-design of the product since the "squaring" of the iPhone
4. The iPhone 5 marks Apple's first time moving beyond their 3.5-inch
touchscreen comfort zone, with the introduction of a lengthened 4-inch
screen. An estimated 2 million units have already been sold via Apple's online pre-order system.

The member of the iPhone family to divert from ithe 3.5-inch screen, the iPhone 5 boasts a 4-inch Retina display with a resolution of 1136 x 640 and 326 pixels per square inch. The iPhone 5 also re-introduces the front-to-back manufacturing model that was last seen with the iPhone 3GS. (One wonders if Foxconn, the electronics manufacturer of choice for Apple, had any influence in the change, as front-to-back manufacturing makes for easier assembly).

Since the introduction of the iPhone by Apple in January of 2007, the handset has been the very definition of "iterative improvement."

The first iPhone, with its multi-touch screen and application-based environment, was considered revolutionary to the smartphone segment. Since that time, there has been five generations of iPhone models, each one improving on the model preceding it. The iPhone 5 is marketed as the most dramatic improvement of any new model, but does it really differ that much from its predecessors? Let's take a look inside to understand what changes at the component level the iPhone 5 reveals.

The front of the iPhone 5 communications board (click on image to enlarge and expand).

There is three MEMS microphone in i-phone5.
I checked two MEMS Part no.
The first of three microphones comes out of the iPhone 5 along with the Lightning connector assembly.
It is safe to assume that the microphone located at the bottom front of the device is used for voice commands and voice calls.
PART NO NE2606 MEMS microphone seems to be in digital microphone
from Analog Devices or AAC.
If you know a more detailed information , sharing reveal.
The rear-facing microphone partners up with the rear-facing camera for recording video, and is also used for canceling out background noise when on calls.
Part no S949 369S MEMS microphone is similar to Knowles MIC Part no. (Analog)
and the other MIC information i don't get.

@goafrit,Dylan, This was the article which speculated ADI has the MEMS microphone socket in iphone5.
